I am looking for a simple password splash screen. In order to get past a spash screen you will need to enter a password. The password would be distributed to users that need to have access to that Flex Viewer app. Not an user name and password.
I did something like that, did not want to mess with securing the web services, although that is a good practice since your rest end point would be more secure. If you just want to enable password protecting the web application without securing the webservice, then go here, there is some code I posted with simple instructions.

One good solution is to take advantage of the security options in your web server. The details would depend on if you're using IIS, Apache, etc.
A very basic, simple, but not secure, option would be to just have a javascript prompt on startup check if they know the password. This might suffice for some scenarios.
